[0002] A bus station is a place for buses to dock. It is mainly set up at the starting point or the end point of a bus station and is used for bus maintenance, refueling, and charging. With the promotion of new energy electric vehicles, buses have also been changed from oil vehicles to electric vehicles. Bus stations need to set up more charging piles to meet the use of new energy buses. At present, charging at bus stations requires manual removal of the charging head and inserting the charging head into the charging port of the bus. After charging, the charging head needs to be unplugged in time. Manual removal of the high-voltage charging head poses a risk of electric shock, and this charging method is too traditional.

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0014] Embodiment 1, as Figure 1-5 As shown, the present invention provides a technical solution: an automatic charging device for buses used in bus stations, including a bus 17, a charging pile 13, a charging head 9, and a charging head automatic search for a charging port structure, the charging head 9 is electrically connected to the charging pile 13 through a wiring harness, and the charging head automatic search for a charging port structure includes a track seat 1, a servo push rod A3, a fixed seat A4, a servo push rod B6, a fixed seat B11, a servo push rod C7, an industrial computer 12, and a groove seat 14; A track groove 8 is provided on the top surface of the track seat 1, a slider is provided on one side of the fixed seat A4 close to the top surface of the track seat 1, and the slider is slidably provided inside the track groove 8, a frame 2 is fixedly installed on the top surface of the track seat 1, a servo push rod A3 is fixedly connected to the frame 2 by bolts on the outside, and a push rod of the servo push rod A3 is fixedly connected to a surface of one side of the fixed seat A4, a fixed seat B11 and a fixed seat A4 are arranged perpendicular to each other, a servo push rod B6 is fixedly connected to a surface of the fixed seat A4 by bolts on the outside, and a push rod of the servo push rod B6 is fixedly connected to a surface of one side of the fixed seat B11, and a button switch 5 is fixedly provided on a surface of the fixed seat A4 facing the fixed seat B11; The servo push rod C7 and the servo push rod B6 are both located on the same side of the fixed seat B11. A base is provided at the bottom of the servo push rod C7 and the base is fixedly connected to the surface of the fixed seat B11. The push rod end face of the servo push rod C7 is fixedly connected to the charging head 9 by bolts. The charging head 9 runs through the surface of the fixed seat B11. A proximity sensor 10 is provided on the side of the fixed seat B11 away from the servo push rod C7. A right angle bracket is provided outside the proximity sensor 10 and the right angle bracket is fixedly connected to the fixed seat B11 by bolts. Two pressure sensors 15 of the same size are arranged horizontally and aligned on the inner wall surface of the groove seat 14 .

[0015] In a specific embodiment of the present invention, the height of the charging head 9 from the ground is consistent with the height of the charging port of the bus 17 from the ground, the fixing seat A4 can slide along the track groove 8, the fixing seat B11 can slide along the surface of the fixing seat A4, and the reflective strip 16 can guide the driver to pour the bus 17 into the groove seat 14 area, so that the rear wheel group of the bus 17 triggers the pressure sensor 15 at the same time. At this time, the processor of the industrial computer 12 receives the electrical signal of the pressure sensor 15. After signal processing, the push rod of the servo push rod A3 slowly extends. At this time, the fixing seat A4 and the fixing seat B11 are connected to the fixing seat A4. The seat B11 slides as a whole. During the process, if the proximity sensor 10 detects an obstacle, the processor of the industrial computer 12 receives the signal of the proximity sensor 10 and controls the push rod of the servo push rod B6 to retract until the proximity sensor 10 detects no obstacle signal. The servo push rod B6 is stationary, thereby avoiding scratches or collisions when the charging head 9 approaches the bus 17. When the button switch 5 contacts the rear surface of the bus, the processor of the industrial computer 12 receives the signal of the button switch 5 and controls the push rod of the servo push rod A3 to stop moving and control When the servo push rod C7 extends out a set distance and the button switch 5 contacts the rear surface of the bus, it indicates that the charging head 9 and the charging port of the bus 17 are in a horizontally aligned state. The servo push rod C7 extends out a set distance and the charging head 9 can be inserted into the charging port of the bus 17. In order to ensure that the charging head 9 and the charging port of the bus 17 are in a horizontally aligned state when the button switch 5 contacts the rear surface of the bus, the charging head 9 and the charging port of the bus 17 can be horizontally aligned in advance when the button switch 5 contacts the rear surface of the bus. When used for subsequent automatic charging, accuracy calibration is performed every week to ensure that the charging head 9 can be accurately inserted into the charging port of the bus 17. The charging pile 13 is connected to the bus 17 through the charging head 9. A charging monitoring component is set inside the charging pile 13. When the bus 17 is fully charged, the charging monitoring component can transmit a signal to the processor of the industrial computer 12. Through program operation, the processor of the industrial computer 12 automatically controls the servo push rod C7 and the servo push rod A3 to retract and reset, so that the charging head 9 is separated from the bus 17, and there is no need to manually remove the charging head 9.

[0016] In the preferred technical solution, a sliding groove is provided on the side surface of the fixed seat A4 facing the servo push rod B6, and a limit block matching the sliding groove is integrally formed on the side surface of the fixed seat B11 facing the fixed seat A4. The limit block is embedded and slidably connected with the sliding groove, so that the fixed seat B11 can slide stably along the side surface of the fixed seat A4.

[0017] In the preferred technical solution, the top plane of the groove seat 14 is flush with the ground of the bus station, the groove of the groove seat 14 is arc-shaped, the groove depth of the groove seat 14 is set to 20 mm, and the arc-shaped groove is set to facilitate the driver to judge whether the rear wheel reaches the groove seat 14 area.

[0018] In the preferred technical solution, reflective strips 16 are provided on both sides of the outside of the groove seat 14. The two reflective strips 16 are parallel to each other. The reflective strips 16 and the groove seat 14 are arranged perpendicular to each other. The reflective strips 16 are attached to the ground of the bus station. The reflective strips 16 can guide the driver to back the bus 17 into the groove seat 14 area.

[0019] In the preferred technical solution, the distance from the charging head 9 to the ground of the bus station is consistent with the distance from the charging port of the bus 17 to the ground of the bus station, and the spacing between the two pressure sensors 15 is consistent with the spacing between the rear wheels of the bus 17, ensuring that the rear wheels of the bus 17 can accurately trigger the two pressure sensors 15 at the same time.

[0020] Working principle: The reflective strip 16 is used to guide the driver to back the bus 17 into the groove seat 14 area, so that the rear wheel group of the bus 17 triggers the pressure sensor 15 at the same time. At this time, the processor of the industrial computer 12 receives the electrical signal of the pressure sensor 15. After signal processing, the push rod of the servo push rod A3 slowly extends. At this time, the fixed seat A4 and the fixed seat B11 slide as a whole. During the process, if the proximity sensor 10 detects an obstacle, the processor of the industrial computer 12 receives the signal of the proximity sensor 10 and controls the push rod of the servo push rod B6 to retract until the proximity sensor 10 detects no obstacle signal. The servo push rod B6 is static. To prevent the charging head 9 from being scratched or collided when it is close to the bus 17, when the button switch 5 contacts the rear surface of the bus, the processor of the industrial computer 12 receives the signal of the button switch 5, and can control the push rod of the servo push rod A3 to stop moving and control the servo push rod C7 to extend a set distance. When the button switch 5 contacts the rear surface of the bus, it indicates that the charging head 9 and the charging port of the bus 17 are already in a horizontally aligned state. The servo push rod C7 extends a set distance, and the charging head 9 can be inserted into the charging port of the bus 17, thereby automatically charging the bus 17, and there is no need to manually take the high-voltage charging end for manual charging.
